Almost one year after police say Luke Chrisco hid in a portable toilet to spy on women at Boulder's Hanuman Festival before running away covered in feces, the yoga festival is not taking any chances with its bathrooms at this weekend's event.

The festival's organizers on Tuesday said they have upgraded the model of portable toilet they will use at this year's festival, which kicks off Friday and runs through Sunday. Spokeswoman Marsha Austin said the Hanuman Festival has ordered Liberty Waste Management's "presidential VIP" model of portable toilet, which will prevent a repeat of last year.

"Structurally, it's impossible," Austin said of someone hiding in the toilet's tank. "We've upgraded the quality and type of portable toilet."

At last year's event, a woman told police she noticed something moving in one of the portable toilets. A man -- who investigators later identified as Chrisco -- then emerged from the toilet and evaded security before running off.

Austin said the festival has added security personnel around the portable toilet area this year, as well. While organizers are ramping up security efforts because of last year's "potty peeper" incident, Austin said they don't expect any copycats.

"It was a unique and isolated incident with an obviously unique individual," she said. "I would be shocked if it happened again."

In fact, while the "potty peeper" episode garnered nationwide attention, Austin said the festival itself hasn't received any additional exposure due to the story.

"We really haven't, and that's OK with us," she said. "We want to be known for the yoga and the music and the vibe and the positive experience people have at the festival. Not because of the facilities, so to speak."

The Hanuman Festival is expecting about 1,200 people over the weekend, a 20 percent increase over last year. But Austin said that is due to expanding the event's reach across social networks and not curiosity about the Chrisco case.

"We have done extensive work across social media, and it hasn't come up," she said.

Chrisco currently is undergoing an evaluation to determine whether he is competent to stand trial on burglary and unwanted sexual contact charges.

In addition to the Hanuman allegations, Chrisco told Boulder and University of Colorado police that he hid in crawl spaces and bathrooms around Boulder, including at CU, Naropa University, the Department of Motor Vehicles office and several businesses, to watch women use the toilet. Police later found physical modifications at many of the locations that matched Chrisco's descriptions.

Boulder is pretty good at producing rock bands, and by "rock," we mean the in-your-face, guitar-heavy, leather-clad variety — you know, the good kind. For a prime example, look no farther than BANDITS. Full Story
